"If you want to start using driverless cars, accurate map information is fundamental," Dan Jaksa at Geoscience Australia tells the BBC. "We have tractors in Australia starting to go around farms without a driver, and if the information about the farm doesn't line up with the coordinates coming out of the navigation system there will be problems." To fix it, Geoscience Australia is updating the country's latitude and longitude to better reflect its actual location.

Those new coordinates will be released in 2017 but will be based on projections for 2020. By the time 2020 rolls around and the coordinates are accurate, Australia hopes to have switched to a new system that takes the continent's drifting—about 2.75 inches per year—into account.
